Namespace:  System.Reflection
Assembly:  mscorlib (in mscorlib.dll)
public virtual Type ReturnType { get; }

Property Value

Type: System.Type
The return type of this method.

Implements

_MethodInfo.ReturnType

To get the return type property, first get the class Type. From the Type, get the MethodInfo. From the MethodInfo, get the ReturnType.

The following example displays the return type of the specified method.


using System;
using System.Reflection;

class Mymethodinfo
{
    public static int Main()
    {
        Console.WriteLine ("\nReflection.MethodInfo");

        // Get the Type and MethodInfo.
        Type MyType = Type.GetType("System.Reflection.FieldInfo");
        MethodInfo Mymethodinfo = MyType.GetMethod("GetValue");
        Console.Write ("\n" + MyType.FullName + "." + Mymethodinfo.Name);

        // Get and display the ReturnType.
        Console.Write ("\nReturnType = {0}", Mymethodinfo.ReturnType);
        return 0;
    }
}

Void return type checking syntax
MethodInfo mi = MyType.GetMethod("MyFunction");
if(mi.ReturnType != typeof(void)){
    //do something
}
Example of void funtion would be usefull
There is no information how to test for void functions aka. Subs in VB. Testing for void functions is one of the most common tasks associated with this property. However it is not clear to everyone that a type System.void exists (and it looks like that it exits solely for this property).

Searching the web for a solution to this problem, I also found that people don't how to correctly test for this type.

I suggest to include in the sample code how to test for void functions.
